Re: [avr-llvm-devel] Current Status?

[John M. <ato...@gm...>]

Hi Sherard,

Borja was working on a re-write of the llvm code. What's in llvm trunk now
has a lot of bit-rot so spending too much time on it before the new code is
committed would be a waste.

Borja's mentioned we need more test cases to spot regressions. We have some
test cases but they're not organized or in the format that the LLVM tools
use.* So one helpful thing would be to create/document/organize test cases
and then also make them work with the LLVM regression test system. *

There's also plenty of work for the Clang and Dragonegg front ends.

Dragonegg [http://dragonegg.llvm.org/] is the gcc front end. There will
probable be a lot of people who will prefer to tryout LLVM through the more
gradual transition via Dragonegg. I've added some skeleton files but
basically nothing been done with Dragonegg. *So creating an AVR-Dragonegg
port is needed.*
*Building/testing an avr-gcc version that works with plugins (aka
Dragonegg) also needs to be done.* I believe avr-gcc needs to be compiled
to support LTO and plugins.

*Getting the avr patches to apply cleanly to the current LLVM trunk
probable is needed also.* This should be simple task.


Thanks,
John
